Q. "What do you mean by the pipe must be restrained?"
A. Unlike threaded fittings, compression fittings can seal properly but still slip out of position as a result of forces on a pipe. The compression joints provide a positive seal but do not restrain pipe from thrusts and movement under pressure. Proper installation of a compression joint requires blocking connecting pipe to prevent any movement.
Q. "When are these sorts of fittings used?"
A. "Dresser" couplings and tees are designed to be used for quick connections, system modifications or repairs. Most commonly these are used for repairing sections of old galvanized pipe where it's too difficult to thread the pipe ends. Some municipalities have regulations about where and when galvanized compression fittings can be used, so double check with your local inspector.
